A vertically disposed guide =bracketindicated generally by the umerainan-is mounted uponthe outer end of the-horizontal-oriower portionof thes ipport panel 24'; and'as shown in Figure 7 eqn prises a pairofparalle1---horizonta1 'leg memhers 512 and-4Q having a' pairefparallel-vertically disposed guide rods' iiiand 48 integrally secured treto. The'ie'gsfiz and 214 are provided with fastening 156 -scre'wthreaded1y engaged thereon wlireiiy me? guide bracket 40 is secured tothe panel. The horizontal leg 34 of the slide 28 is disposed in thevertical guiding slot between the member 48 and the adjacent surface ofthe panel 24, while the horizontal leg 38 of the slide 36 is disposedbetween the guide rods 46 and 48 and are thus vertically slidablebetween the upper and lower legs 42 and 44, and are capable ofindependent tilting motions therein as shown by examining Figures 3, 9and 10.

Upon the vertical portion of the panel 24 there is provided a pair ofguide hooks 52 and 54 which are disposed on opposite sides of the slide28 and are spaced vertically therealong as shown clearly in Figure 3.The arrangement of hooks is such that pivoting movement of the L-shapedslide 28 in a counterclockwise direction as shown in Figure 3 isprevented, but a clockwise pivoting movement is possible as will be seenby comparing Figure 9 with Figure 10. To the upper end of the slide 28,is secured a cable 56 by which the slide is vertically reciprocated uponthe panel for a purpose which will be later set forth.

Secured to the horizontal leg of the panel 24 on the opposite endthereof from the guide bracket 46, see Figures 3, 5, 8-10, is a guidestrip 58 upon which is mounted a guide bracket 66. The space or slotbetween the bracket 60 and the guide strip 58 is disposed in parallelarrangement to the space between the members 46 and 48 of the guidebracket 40 and with the latter space constitutes a guide slot in whichis vertically reciprocable the horizontal leg 38 of the slide 36. Itwill be observed that the slide 36 and the horizontal leg 38 are spacedoutwardly of the panel 24 from the slide 28 with its horizontal le 34,the slides 28, 36 thus lying and moving in parallel vertical planes, sothat no interference between these slides will be possible during theirsliding and tilting movements.

The slide 30, at the junction of the vertical and horizontal legs 36 and38, is provided with an apertured lug 62 and the end of a cable 64 issecured thereto by which the slide is vertically reciprocated upon thepanel for a purpose .to be subsequently made apparent.

As seen from Figure 6, the lower corner of the support panel 24 isprovided with a notch or cutaway portion as at 66 and a stub axle 68 isfixedly secured to the panel upon what may be termed its rear side, thatis, upon the side opposite the brackets 60 and 46, this stub axle beingsecured by welding as at I and extending into the notch 66. A guidepulley 72 is journalled upon the stub axle and retained thereon by athreaded nut I4, and the above mentioned cable 64 extending downwardlyfrom the lug 62 is entrained over this guide pulley and from thenceextends upwardly behind the back side of the panel as will be seen fromFigures 2, 6-8.

Referring now to Figure 2, it will be seen that the cables 56 and 64 arerespectively entrained over further guide pulleys I6 and I8 which arerespectively carried by support brackets 80 and 82 detachably secured onthe frame I0 of the loom and are then positioned horizontally across thetop frame of the loom and after passing over further guide pulleys 84and 86, respectively, extend upwardly and are attached to the customaryJacquard cards and control the head mo-' tion of the loom. Thus, thecables 56 and 64 will be moved in synchronization with the head motionto cause vertical reciprocation of the slides 28 and 30 insynchronization therewith.

It Will be noted that the horizontal leg 38 of the slide 30 is providedwith a collar 88 fixedly secured thereto which is adapted to bearagainst and abut the left hand side of the guide 46, as viewed in Figure3. This collar prevents sliding movement of the horizontal leg 38towards the right, although movement toward the left is possible.

Between the guide brackets 60 and 46, the horizontal leg 38 has securedthereto in a desired manner a tension spring 90 Whose D1 end is fastenedin any desired manner to the support panel 24. It will be noted, asviewed in Figure 3, that the upper end of the spring 90 is disposedabove and slightly towardthe right of the fastening of the spring uponthe horizontal arm, whereby the tension of the spring will both pull theslide upwardly, and also urge the leg 38 of the slide towards the right,with the collar 88 in slidin abutting engagement with the guide bracket40.

The vertical arm 36 of the slide 30 is slidably received beneath twoL-shaped slide hooks 92 and 94 which are mounted upon the support panelwith horizontal supporting legs and lateral arms extending over theadjacent vertical edge of the panel. The vertical leg 36 of the slide 30lies outwardly of, Or against the left side of the legs of the hooks 92,94, as shown in Figures 3, 9 and 10, this arrangement preventing tiltingof the slide 36 in a clockwise direction as viewed in Figure 3, butpermitting counterclockwise tiltin as shown in dotted lines in Figure 3and in Figure 9.

Secured to the vertical leg of the support panel 24 and preferablyslightly above the guide hook 92, is a laterally extending guide stripmember 96 which is welded or otherwise secured to the front surface ofthe panel 24 and extends laterally beyond the edge thereof. The topsurface of the strip lies in the same vertical plane as the top surfaceof the guide member 58 and of the guide surface of the guide rod 48, andwith those members serve to slidingly support the undersurface of theslide 30, engaging its vertical and horizontal legs 36 and 38respectively. The member 96 extends sufiiciently laterally and outwardlyfrom the support panel 24 to guide and support the guide 30 when thelatter is in a tilted position as shown in dotted lines in Figure 3 andFigure 9.

Welded or otherwise fixedly secured to the front surface of the supportpanel 24 and between the slide hooks 92 and 94 are a pair of parallelsupporting lugs each indicated by the numeral 98. A lever I06 is pivotedto the lugs 98 therebetween, and has pivotally attached to its oppositeends an actuating link I02 and a cable I04. The link I02, see Figure 4,is pivotally attached to one end of a lever I06 which extends through aslot I08 in the support panel 24 and is pivoted intermediate itsextremities to this panel as by pivot pin III]. By means of the hookfastener II2 secured to the same end of the lever I66 as the link I02but at the opposite side thereof, a cable I I5, see also Figures 1, 2and 9, connects the levers I06 and I00 with a loom stop motion Ill whichmay be mounted upon the front of the loom frame I0 and may be of thetype and construction set'forth' in my prior co-pendin applicationsSerial Nos. 208,345 and 214,377, filed January 29, 1951, and March 7,1951. The cable I64 may extend to any convenient location, as to therear of the loom, and comprise manual operating means for the levers I00and I06.

As'So far descri=bed;r"it will be apparent thatthe tilting movements of'either of the slides 28"an'd 30 will thus be efiecti've' to tilt 'thelever l 86 in' a clockwise direction'as viewed in" Figure 4' and thereb/actuatetnestopmotion H1.

On. the rear side of the panel 24 as snewnmcre clearly in Figures 4, 6,'7 and 8, the upper end of the lever we is attached to a -link l 13,,which -in turn is'connected with an electric switch H4 of anysuitabiedesign- "and iermingparr'or the electric power circuit of theloom: It will thus-be apparent that upon actuatiorr-offithe lever- 106,the-switch will be actuated in turn, and in an'y desired manner willstop the operation of the loom. As hereinbefore set forth, the cable [04comprises a manual means actuatable remotely, for stopping the loom bytripping the switch H4 or the stop motion I [7.

Referring now again to Figure 1, it will be seen that the stop motionattachment of this invention is mounted upon the frame of the loom insuch a manner that the horizontal legs 38 and 34 of the slides 28 and38, are disposed respectively between the top and bottom beams l4 and I6of the batten i2, and between the bottom beam 56 of the batten and thereed lay [8. In this position, the vertical motion of the batten and thearcuate horizontal and vertical motion of the reed lay will cause themembers l4, l6 and I8 to move both vertically with respect to thehorizontal legs of the slides. By the cables 56 and 6d, the slides arelikewise caused to move vertically in timed relation to the verticalcomponent of the batten motion so that no pressure is applied to thehorizontal legs by the motion of the batten, when the head motion andbatten are properly synchronized. However, if for any reason the headmotion of the loom fails to function as called for by the pattern cards,there will be corresponding failure of the cables 56 and 8G tovertically reciprocate the slides 28 and 30. Consequently, the verticalcomponent of motion of the batten will then tilt whichever of the slidesis not vertically reciprocated in timed relation thereto, therebycausing through the tilting of that slide actuation of the switch H4 andof the cable I I5 and stop motion II! to thereby stop the operation ofthe loom.

The operation of the loom with this head and batten stop motionattachment applied" thereto is as follows: The cable 56 is pulled up bythe hooks of the Jacquard head and as the blades of the Jacquard headraise and lower, the hooks of the Jacquard head rise and fall, liftingthe slide 23 and permittin the same to drop in synchronization or timedrelation to the rise and. fall of 6. th e' beittirby tlre side metre Jthe head anebetted: and feed la'y are 0 the batten bar it does not applypressure to -the" hofi zonta-l -leg 34 5f theslide 'i'a' arid therefoi"ethe "latter" reciprocates*verncany Without writings If the head" andbetterget outer 'tli'fif'sdthxt the :baaea does not raise-atthdtinl'e'required" by the-head motionfwhiclrattherequird'timeraises tlf slide thestationary batten bztl H3 Will-fir?- plya downwardly and; a clockwisetiltingpres'sure to= t1i u per=surfateor the'vei'tically ascending leg'34, "which will tilt the slide 28" to thepo'sitioh shownin F u IO/thusactuatingthe lever 106, which through" link l 3 will actuate the switchI M ancl 'througlr cable I i5 "will actll'aite the stopmotio'n" l Fl -tostop theloom:

It is evident that this mechanism can be applied on various convenientportions of the loom frame since the flexible cables 56 and 64 willpermit easy attachment of the mechanism to the head motion of the loom.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to 'beunnecessary.
